Yes his comments is rude, but I think if you would a bit more compassionate for a young man whose health is in jeopardy, you could understand that he's a bit angry right now. It also doesn't necessary mean that he's a "troll" that you attacked him with. None of us have an answer to what happened to his situation, and perhaps we should pay attention, learn and be understanding. It may have been better for you to ask some questions instead of call him a "troll" which was unproductive.
